For the first time in nearly a century, 33 & 35 Shell Street are being offered for sale together. Originally acquired in 1929, this cherished cornerstone of 'Sconset history has been enjoyed as a beloved family compound for generations. Unrivaled in both location and scale, the estate represents a true once-in-a-lifetime legacy opportunity. Commanding an expansive and elevated vantage point with sweeping, unobstructed 180-degree views of the Atlantic Ocean, the compound seamlessly pairs a stately Main House at 35 Shell with a charming Guest House at 33 Shell. The compound is beautifully complemented by a classic three-bay garage and magnificent, deep oceanfront lawns that lead to direct, deeded beach access. The Main House is designed with flawless flow and architectural symmetry. A grand central living room anchors the home, separating two distinct wings and offering immediate visual drama upon entry. In the North Wing, a formal dining room with expansive views and direct deck access is supported by a gourmet kitchen, butler's pantry, and a dedicated office and mudroom. The South Wing serves as a private retreat, offering a cozy den with a fireplace alongside a private two-room guest suite complete with its own sitting room and full bath. For effortless entertaining, the dining room, central living area, and den all open directly onto a sweeping ocean-view deck-perfect for al fresco dining or shaded afternoon relaxation. Dual staircases-one positioned in each wing-enhance privacy and provide exceptional internal circulation to the upper floor, which hosts nine of the property's ten-plus bedrooms. The guest house offers an additional six bedrooms (two are ensuite), and three full and 2 half baths. The exterior grounds are an entertainer's dream, defined by the expansive oceanfront lawn and two private, hedge-lined patios beautifully configured for firepits, lawn games, and lounge seating. The grounds are complete with two outdoor showers, and the property has HDC approval for a pool. More than just a home, 33 & 35 Shell Street represents an irreplaceable piece of Nantucket's heritage. Welcome to the ultimate 'Sconset legacy. (Note: 35 Shell Street (Main House) can be purchase independantly from 33 Shell for $15,975,000)
